Yeah. Sure. Turkey can make airplanes. Great.
They still need help with a lot of things. Can you name any Turkish companies that build packet sniffing hardware? That design special ASICS for this? Content filtering solutions? Specialized networking gear? Maybe, but probably not.
The vast majority of countries that have 'controlled internet' scenarios cannot do it themselves, or rather, it would be very difficult to do.
In fact - which countries could do it alone ...
Russia, China, surely. India. Turkey ... probably not.
Saudi, Morocco, Jordan, Egypt, Indo, basically every country in M/E and Africa, pretty much all of South America (maybe Brazil?), probably not Pakistan, not North Korea.
Forget 'Western' - there are just a few countries that could do it alone, depending on the degree of sophistication of control. Basically West/North Europe, USA/Can, Japan, S. Korea, Russia, China, India ... Singapore even is probably too small. It's not a long list.
